The present invention relates to roadjfin ishing machines and has for one of its objects to provide a machinethat will operate upon the road in a lengthwise direction to :listribute road making material thereover and will at the same time finish the surface thereof, thereby eliminating manyof the bumps and rough places in'the road not overcome by machines operating in a A further object is to so constru'ct'the traction mechanism of the machine that the showingtools for adjusting the drum carryside frames of the concrete road may be utilized as tracks for. thefinishing machine in which all oscillating side thrust is elimi nated and by meansof which a crowned surface of the road may be gradually changed to a flatsurface. r

A further object is toprovide a machine for use inroad building which will simul-- taneously shape and finish the road, and which will spreadand distribute them'aterial of which the road is being built.

A further objectis to provide for adjustthegmachine is moving backward over the work or for any other purpose.

A further object is to provide a machine which will finish the road free from bumps and rough places and willpushforward the surplus materialof which the road is contute part of ,thisspecification:-

Referring to thedrawings in detail by reference numerals, the same numerals des ignating' the same parts in all figures of the-drawings, lOdesignates a=main frame WhlCll maybe considered as stationaryrelative to the supplemental frame 11 which is;

hingedly mounted as at 12 uponadrive shaft 13 'journaled in the frame 10. The

frame 10 is provided withtransverse axles 14: "upon which are rotatably mounted wheels15,- while similar wheels 15 are similarly mounted 'onlthe ends -ofv the drive flanges 15a on one 'side -the'reof. The axles tion relative thereto and the wheels of the shaft 13. The wheels are provided with drivev shaft are provided on the flanged 17 slidably andnon rotatablymounted upon thedl'rive shaft 13, the clutchesbeing=prevented from rotary movement by means ofpi lugs 18 projecting into suitablelgrooves i ex tending longitudinally of theff'shaft. i The j cl'utches 17 are movable longitudinally- 0f the shaft by rneans of a} yokedlever'inem side's thereof with projecting clutch'mem-- bers l 6,-adapted to co-ope'rate with clutches bers 19 pivoted as at 20 to suitable supports ing lugs 24' at their lower ends abutting against the inner side of the lever 19 to cause rocking movement of the said lever members when the operating lever is moved in one direction while movement in the opposite direction will not effect the position of the lever members 19.

By this arrangement, the clutches on the" 1 opposite sides of the machine which it will chine should 'one side move ahead of the '20 members converging toward thecenter of the ,3, machine and forming a support for vthe be noted'are connected only with rear axles,

may be thrown out of engagement with the.

clutches ofthe traction wheels 15 selectively, thereby. permitting therighting of the maother; The rear wheels 15, are in driving connection with the front wheels through sprockets 25 formed thereonand sprocket,

chains 26 cooperating therewith.

J ournaled to the supplemental frame 11 :are verticalshafts27', which carry at their lower ends-surfacing and finishing drums 28, the supplemental frame 11 comprises upper and lowermembers 11a and 11?) upon bothof which members are secured the journals 29 and 30 for the shafts 27. I Theframe .members 11a and 11b extend forwardly ofthe machine/from each side thereof,-said shafts 2.7 so that thedrums 28 will lie'in staggered relation to each other from the; apex-as at 118.71, each-drum being disposed.

whereby the, path of adjacent disks overlap 'a suitable distance, so that no portionof; {the road will I escape being operated upon thereby; y'ThG shaft -13 is in driven connection witha motorl31- which is mounted upon a the machine,-through sprocket wheels32 and 33 respectively mounted upon the shaft 13 and upon the drive shaft 34,: of the motor,; the sprockets 323 and 33 being :connected 7 7 I44 and 45 on the end shafts 27. and when itis i by means of sprocket'chains The upper ends of; the shaft 27 are provided with: sprocket .wheels 36 secured thereto and are;

mounted upon a stub shaft 40 which is pros shaft 13 as at 12, it will be readily under vided with beveledgears 41 articulating with beveled gears 42' on theshaft 13. The belt 37 is maintained-in contact with the sprocket wheels 36 on the ends of the shafts 27 means of idlers Q43 placed between the said sprocket wheels androtatably' mounted on the upper member 11av of the supplemental 1 frame; The belts 37Iand138are-causedito rotate in opposite lvdirections, the forward v part of the belts moving? outwardly toward the sides .of the; machine for rotating-each" F setof drums operated thereby accordingly.

in opposite directions. In other words one set is rotated in a'clockwise direction, while On the ends of two These sprockets as shown are mounted on the end or outermost shafts and are rotatable relative to said shafts and-gare' pro-- vided with crank arms46 and 47 for rotating thesame. At intermediate points of the frame are providedscrew shafts 48 and 49 to which frame members 11a and 11?) are secured by means of collars 110 against longitudinal movement relative thereto, the

shafts 48 and 49 being 'journaled in said frame members for rotation relative there to and having threaded connectionwith col lars 50 secured to a crossmemberlOa to the stationary frame 10. The shafts 48 and have secured thereto at. their upper ends I sprocket wheels 51 and 52 about which together with the sprockets 44' and 45 is trained a belt 53. By this construction by the rotation of the crank arms 46 and 47,

itcwill appear, the supplemental frame 11 maybe raised upwardly lifting the drums" 28. off thesurface of the road when such 7 operation s desired for any, purposeas forv moving the machlne rearwardly over a sur-' 7 face which has been worked upon.

It is believed that from the foregoing scription, the operation willgbe apparent V '7 which" is however, briefly as follows: When a it is desired to use the m'achinein themaking of a road, the machine is placed thereupon in the position such as shown in Figure 1 with the wheels 15 resting on the'marginal" iron forms 54-laid along the sides and; forming the edge ofthelroad, two wheelsof. the machine, one on each side Jareconnected with the drive shaft 34 'of the motor through the sprockets 321and 33, sprocket chain- 35 and drive shaft 13 and by means ofwhich the machine is propelled alongthe roadway,

the drums 28 being rotated jthrough the shafts 40, the sprockets 39 and the sprockets desiredto raise the drums off the ground, I

the crank arms 46 and 47 are rotated where upon the threaded shafts 48 and 49 willraise Y the forward end of the supplemental frame .11 lifting the drums 280f]? the ground. The

frame 11 being hingedly connected tosthe stoodthat the front drum 28 will be raised nism to gradually change the; surface of a road from a fia't to' a crown finish 'or vice y versa.

In making the roacL'theimatria1.owliich :the road is tobe constructed is dumpedout on the subgrade inpiles and themachine is moved along the side rails as stated above, and as each pile is reached it is spread and distributed evenly over the surface of the subgrade, the surplus material being pushed forward and the drums 28 rotating finish the surface as it progresses. Owing to the arrangement of the drums, material will not be permitted to pass to the rear of the machine or be left in unfinished condition. Should however, the distribution and finishing be incompleted by the passing of the machine, the drums may be raised off the ground in the above manner and the direction of the machine reversed and backed to the rear of the imperfect portions of the road. The drums may be again brought into contact with the road and the machine moved forward.

A device of this character moving longi tudinally of the roadway will produce a completely finished road of concrete or other road making material in a smoother and more uniform manner than the ordinary process now used by which the smoothing )f the surface is accomplished by a transverse moving machine or the like, and my device will not only evenly distribute the material but will finish as wellras properly grade the surface of the concrete or other road making material employed, in accordance with the users desires.

Further the provision of wheels on the side of the machine by which the said machine is guided b the side or marginal relations of the roa will insure uniformity of operation, relative to the roadway.
